    Laser Warning Lumia and difraction wheels

    My production. Lumia glass and star filter. I finally managed to finish the glass star filter. It will go in front of the galvo scanner. I managed to make 2
    pieces. It is not easy to make a filter. Cutting and correctly scoring the glass, a lot of waste, a lot of time until you find the right effect.Today I received the electronics I ordered. It drives two stepper motors, on which the diffraction wheels are placed.

    Old school! One of the old school Laserium fixes for the backlash in our Escap gearhead motors was to put a felt washer between the motor and the effect hub to keep the effect from "skipping". Having the pickoffs enter and exit the beam path is a nice technique too. Avoids scatter getting through "inactive" effects and allows for interesting cross fades.

    I made six lumia wheels. I also have two pieces of double lumia wheels plus optics. Breathtakingly beautiful effects.:bomba:Of course, choosing the right glass, combining it was and still is alchemy. It is a long process to find the right glass and combination for a double wheel, plus adjust the optics. And I must not forget to remind you. It is important to find the right engine with revolutions.Double lumia sample. Two types of wheels are used. The first wheel shows a nebula with cracks. Hundreds to thousands of cracks with bubbles. The second wheel projects a lightning simulation.

    Laserium often used a rotating effect wheel with a stationary effect above it. Also two wheels with different dc motors that allowed different speeds and directions.

    Love that hobnail glass! I have found it to be excellent lumia media. It makes for some very complex, almost background-like, patterns with a wide but pleasing spread; perfect to nestle abstracts in!
    Those who fail to grasp art are the ones who criticize it.

    I agree, I already used it at the beginning when I got to know lumia.
